This page represents an arbitrary SNP. The main text body of a SNP page summarizes the associations between SNP variants and a range of human traits (body height, disease risk, response to drugs, even behavior). The science that supports these associations (peer-reviewed publications with citations) is indicated by links to PubMed abstracts in the form of {{PMID|12345678}} or [PMID 12345678] style citations.

Technically, there was once a valid rs1234, but it has long since been merged into a different identifier, due to the natural changes of that system.

For this reason, on SNPedia, we will use this SNP to explain how to use many key SNPedia features.

To the upper right you will see a box with these fields:

is a snp . This tells you that you are looking at a page about a snp. You may sometimes see the words gene or genotype.

is mentioned by . This will show you what other pages on SNPedia are related to this snp.

dbSNP rs1234 . This will take you to the the graphs of population diversity on its ncbi dbsnp page.

The colored box indicates the frequency of each genotype in 4 HapMap populations. CEU is European so the box indicates that 10% of Europeans are (A;A) colored brown, 60% are (A;C) colored green, and 30% are (C;C) colored blue. The Chinese (CHB) and Japanese (JPT) are mainly (C;C).
